Enum InstanceSettingsError 

#[non_exhaustive]
pub enum InstanceSettingsError {
    AlreadyFrozen,
}

Why configure_instances refused new settings.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AlreadyFrozen

An instance was already made or settings were already configured.
